通过电影摄影进行男子短跑技术的运动学分析。计算机处理分析的参数包括直接动作参数(身体速度、步速等等)和上肢与下肢的运动学参数,这些参数是以前分析短跑运动员曾利用过的参数。比赛名次的优劣与下列动作参数有关:身体水平速度(直接关系)、步速(直接关系)和支撑时间(间接关系)。决定成绩好坏的关键性身体运动学 Kinematics Analysis of Male Sprint Technology through Cinematography. The parameters of the computer processing analysis include direct motion parameters (body speed, pace, etc.) and kinematics parameters of the upper and lower limbs, which are parameters previously used by the sprinter. The pros and cons of the competition are related to the following action parameters: body speed (direct relationship), pace (direct relationship), and support time (indirect relationship). Key body kinematics that determine grades
